I thought the Twitter bots were only supposed to tweet "interesting" questions. This one has a down-vote, (probably worth noting the down-vote happened after the tweet) two close-votes, very low up-front quality, and has been flagged at least once. It's essentially spam, and has also been duplicated by this anonymous user on Unix, Web Applications and Server Fault, as well as in an answer to another thread on Security.

This is not at all an "interesting" question, except that it is one to which moderators should be quickly alerted. It is definitely not an example of one that we would like to see posted by a Stack Exchange Twitter account.
So, what is the threshold and how did this one trigger it?
